- 1 Claim. (o1.1o1 '110 The present invention relates to markinstamping, embossing and similar machines and more particularly to thetype where the matter to be stamped is easily changed and truly aligned.

An object of this invention is to provide a novel and improved machineof the type mentioned employing a series of wheels each havine'qui-spaced marking or embossing characters, as the letters of thealphabet, numerals or other insignia on the periphery thereof; eachwheel being capable by a single means, of being re- 'volved any requiredamount independently of the others, and all to be locked against rotaryinovement when characters composing the matter to be stamped orembossed, are presented in opersting position.

Another object hereof is to provide a machine bf the class set forth, ofnovel and improved con- 'struction where the wheel rotator isautomatiball'y shifted into true operating position with {respect to anyof the wheels, a little ahead of the operators manual manipulation,whereby accuracy of operating position of said wheelrotator is assuredindependent of the operators adjustment, and where the rotary movementof the. wheel from character to character thereon into operatingposition is automatically shifted into true position, a little ahead ofoperators manual manipulation, whereby accuracy of operating position ofeach wheel is assured independent of the operators adjustment.

A further object is to provide a novel and improved machine of thecharacter described where the depth of the embossing or amount ofimpression is controllable.

A further object hereof is-to provide a machine of the class mentionedof novel and improved construction, adaptable for imbedding metal leafinto the impressions embossed on objects, as for instance the names onwood pencils or designs impressed on leather hat bands or gold leafstampings on book covers or similar work.

Still another object of this invention is to provide a novel andimproved machine of the nature described which is simple to set up andoperate,i compact, positive in action, and efficient in carrying out thepurposes for which it is designed.

' Other objects and advantages will become manifest as this disclosureproceeds.

Fig. 7 is a side View of a portion of the machine of Fig. 1, at theleft-hand side thereof.

In the drawings, the numeral l5, designates generally a casing forhousing the stamping or embossing mechanism. A shaft I6, is slidablymounted through said housing and its ends protrude exteriorallytherefrom. Said shaft l6, has a knob l! at one end, and a head [8 at theother of itsends. The head I8 i housed within a hollow knob l 9 of atubular member 20. This member 20, is exteriorally threaded at 2|, atwhich portion it is threadedly engaged with the casing l5. Member 20 isa sleeve on the shaft [6. The chamber 22, isof adimension along the lineof the shaft Hi, to permit a comparatively short longitudinal movementof said shaft thru member 20; head l8 serving to limit such movement.

Said shaft It, carries securely mounted thereon, a gear 23, and also thebrackets 24 and 25,

through which said shaft is rotatable. A plate 26, on which saidbrackets 24 and 25 are securely mounted, maintains said brackets, overat each side of the gear 23, and in contact with the latter, so thatupon longitudinal movement of shaft I6, the plate 26 and the brackets 24and 25 carried by said plate, are moved along with the gear A series ofgear wheels 27, all of identical size and each having the same number ofequi-spaced teeth, are carried on the tubular member 28,

and each wheel is independently axially rotatable preferably are ofheat-insulative material; if it is desired to include a preferablyelectric heating coil 3! within the tube 28 for purposes hereinafterexplained, so that only the wheels 2'! are heatedandthe rest of thedevice substantially insulated from the effect of said heating means.The collars 29 and 30 are securely mounted within the casing l5wherebythe tube 28 is firmly positioned.

The peripheral surface of each tooth of each of the wheels21, isanembossing or stamping element. Forins'tance each wheel 21 'may havethirty-six teeth; so that the embossing or stamping elements wouldcompose the complete alphabet and the numerals from zero to nine. Ofcourse, said embossing or stampingelementmay be of any desired insigniaor character. yThe,respective aligned teeth of wheelsf2l, at position5!, comprise the matter tobe. embossed onto for instance a pencil 32,positioned on Vfblo,ck-3.3Y, ,carried by member 34, the arm 35 of whichis Saidmempivotally mounted at 35 on frame-31..

The actionof spring 50 onball v48, as gear 23 is rotated, will be to automatically urge theoperator to accelerate the rotary movementv of knob [1, for said ball isstrongly urged into engagement with the succeeding hole .49. flit is tobe noted that when ball 43 ,is in any of the holes 45, gear 23 is intrue co-planarzaiignmentLand full engagement with one of the wheels :21,and that when ball t8 is in any of the holes .49, a tooth of suchengaged wheel 2! is in true operating position 3!. When the requiredcharacter of the-first wheel 21 is in position 3|, the knob I9 is againturned counterclockwise to bring gear 23 into engagement with the nextwheel 21 and then knob I1 is again operated, subject to like incident asexplained, as is evident to set all the wheels 21, so that in aggregate,their teeth presented at position 31 comprise the matter to be stampedonto the object 32.

It is important to note that all the wheels 21, are locked againstrotary movement by plate 26, except the particular wheel 21 which isaligned and in engagement with the gear 23. After all the wheels 21 havebeen properly arranged, gear 23 is returned to the extreme left restposition out of contact with any of the wheels 21, in which position,all of said wheels 21 will be locked by the plate 26.

By operating handle 40, cam 38, will raise holder 34, and cause animpression of the stamping or embossing characters at position 3|, ontothe object 32. Return of handle 43, to initial position, will causeholder 34 to fall, and object 32, can now be removed and replaced byanother for repetition of the cycle of operation. The depth ofimpression can be regulated by adjustment of position of wedge 12, tolower or raise the holder 34, and thus initially set same.

The ribbon member 53 may carry an inking substance or, metal foil forinlay into the embossed characters, aided by heat aforementioned, or forgold stamping where the characters are printing type. The operation ofthe feeding mechanism of such ribbon member 53, is effected uponmovement of bell crank 68, caused by pin in its travel with cam 38, onceduring each cycle, whereby pawl 66 will cause a slight rotary movementof rollers 60 and (ii, to present a fresh portion of said ribbon atoperating position 3|.
